Safety Precautions
The Torus turbine model is designed for experienced modellers. This model is not recommended for beginners to R/C flying and should not be attempted by those with insufficient building and flying experience. This
manual is for guidance only. If you are unsure of any model building techniques, seek help from an experienced model builder or contact Boomerang RC Jets, LLC. for assistance. Jet models are dangerous if
construction is carelessly or incorrectly carried out. As the building assembly of this kit is out of our control
after point of sale, no liability is accepted by Boomerang RC Jets, LLC. for any accident or loss, however
caused. Purchase of this kit implies acceptance of these conditions by the purchaser. To decline these
terms, return the unused kit to your supplier for full refund.
NOTES ON HORN POSITIONS
Mount the horns so the clevis holes are 1/4" (6mm) behind the hinge line for the
ailerons to give differential and on the hinge line for rudders and elevators.
But on the FLAP horns, move the horn bolt rearwards about 1"(25mm.) from
hinge line and re-drill the hole for the clevis back so that the hole in the plastic
flag is a full 3/4" back behind the hinge line. This will allow the flap to drop almost
to 90 degrees full deflection.
Insert all hinges and check range of
movement, then apply thin CA glue.
Cocktail stick pin
Be sure to apply thin C.A. glue to both
sides of each hinge. Then pin each
hinge from below using cocktail sticks,
fore and aft of the hinge line. Do not
pierce the top surface.

As With all ARF Kits, it is essential to make
a thorough check of all glue joints and add
epoxy or CA glue if required.

wing tips. Line up and press the tip home while the glue
sets. Then slack off the bolts and release the tip with the

Additional safety fitting to stabilisor
With tailplane (Stab.) firmly
screwed down, pass a 3.6mm
drill through the holes in the fins
and drill a hole through the metal
tongue projecting down from the
Stab. Remove the Stab and tap
the new hole in the tongue out to
4mm thread. Repeat the
process through the other fin.
During assembly apply the 4mm
X16mm bolt through the fins and
the tongues and lock in place
with the 4mm nylock nuts and
washers supplied. If a 4mm tap
is not available drill the hole in
the tongue out to 4mm and
assemble the same way.

braces marked "cut" in the hatch. You
may prefer to fix the turbine with the

use self tapping screws if preferred

RUDDER
FLAP
For your first flights, take the CG with the
model “dry” all assembled with the retracts
down and the hatch removed. If you are
using lightweight batteries you will need to
add up to 16 ounces of weight in the nose.
The CG should be at the centre of the
front carbon fibre wing spar.
Supplementary instruction for Torus Wing Bag
Due to a late design change in the wing tip tanks assembly which permanently
fixes the alloy rods in place, it is necessary to cut a slit in their protective bags to
allow the tanks to be put in.
Make a straight cut, starting from the open end for approximately 18" along the
bottom of the bag. Insert the tiptank, pointed end first. Once the tank is in the bag,
the opening can be held together using elastic bands or Velcro or similar fixing
method.
IMPORTANT WARNING.
READ THROUGH BEFORE ASSEMBLING OR FLYING YOUR KIT.
Just as in any full size aircraft, any RIC model aircraft can be made to fail, be it a wing folding or a fuse­
lage breaking under too high a load. Model RIC aircraft have a maximum safe G limit. Because you are
not in the plane it is difficult to judge the G during flight, and it is very easy to exceed the limits of the
aircraft. This is particularly important if you install a turbine larger or more powerful than the power band
specified for that particular kit. This negates any airframe warranty straight away.
All our designs are thoroughly test flown before the kit is released for sale. Turbine powered RIC model
aircraft are not manufactured to withstand unlimited G forces. When flying your Boomerang Jet, be
aware of the high loads which can be in excess of the airframes capability to handle. Respect the
airframe as you would when flying a full size aircraft. Fit a turbine only up to the specified power.
Understand that if you perfonn a snap roll, wall, blender, knife edge loop or any similar manoeuvre, or
pull hard on the elevator, particularly at high speed, you can over stress the airframe by up to15 G or
more. At 15 G, the 27 lbs (12.2 Kilo) model effectively weighs over400 lbs (184 kilo), and though it may
be for only a few seconds, the strain on the airframe is huge. Your model may survive those hard
manoeuvres a few times, but eventually the cumulative damage will tell and airframe break up can
occur.
It is common practice for any manufacturer not to replace an airframe which breaks in the air or upon
landing. Manufacturers may replace airframes when they have noticed many incidences of the same
failure and it is detennined that there was a design fault or repeated manufacturing error. If you break
an airframe, and you are the only one to do so, then it is highly unlikely to be the fault of the manufac­
turer. Fly safely, and avoid full throttle operation other than at low airspeeds.
RIC model jets are not toys! If misused, they can cause serious bodily hann and property damage. Fly
only in open areas, and AMA (Academy of Model Aeronautics) or BMFA (British Model Flying Associa­
tion) or your country's approved flying sites. Follow all manufacturer instructions included with your
plane, radio, servo's, batteries and engine. Each kit is guaranteed to be free from defects in both mate­
rial and workmanship at the date of purchase. Warranty does not cover any component assembled by
the customer. All parts of high stress must be inspected and reinforced if necessary by a competent
builder.
Some parts should be examined, and if necessary, glued again. High stress areas such as firewalls,
motor mounts, wing mounts, landing gear mounts, etc., are areas of high concern. Seek help if neces­
sary.
In no case shall Boomerang RC Jets, LLC. warranty cover any product which is not manufactured by
Boomerang RC Jets, LLC. The liability to the manufacturer cannot exceed the original cost of the
purchased item.
Further, Boomerang RC Jets, LLC. reserves the right to change or modify this warranty without notice.
In that Boomerang RC Jets, LLC. has no control over the assembly or materials used by the builder of
the model during final assembly, no liability shall be assumed nor accepted for any damage resulting
from the use of the final user-assembled product. By using the user assembled product, the user
accepts all resulting liability. The kits manufacturers have provided you with a top quality, thoroughly
tested kit and instructions, but ultimately the quality and flying ability of your finished model depends on
how you build it. Therefore, we cannot in any way guarantee the performance of your completed
model, and no representations are expressed or implied as to the performance or safety of your com­
pleted model. It is the use�s responsibility to inspect each component for airworthiness.
